The annual release of the Pirelli calendar, which recently marked its 50th anniversary, is always accompanied by a small media frenzy, as the glossy pages traditionally feature artful photographs of Amazonian-bodied supermodels shot by renowned photographers.

But for the long-awaited 2016 Pirelli calendar, released on Monday, photographer Annie Leibovitz shook things up by focusing her lens on muses she described in the press release as “distinguished women,” chosen for their accomplishments rather than physique alone.

Though the calendar focuses on non-nudity, the behind-the-scenes images released in September hinted that some subjects will bare more. And indeed, Schumer and Williams are photographed wearing only underwear.

In the press release, Leibovitz explained that these two portraits were conceptual: April model Williams’s photo was “not a nude but a body study,” while December girl Schumer’s, pictured drinking a latte in her underwear, was meant as a comic whim. “The idea was that she was the only one who had not got the memo about wearing clothes.”

The calendar is not for sale and is only sent to a select few, but the images, which circulate online, are sure to make an impact. The calendar’s May model, cultural commentator Fran Lebowitz summed it in her usual sardonic manner: “Perhaps clothed women are going to have a moment.”

The company’s chief-executive, Marco Tronchetti Provera, added that the tyre manufacturer has been seeking a new direction for its legendary calendar, and that the new format felt “very timely,” as the portraits show “women who have done something outstanding in their lives, from every corner of the world.” “This represents what Pirelli thinks is beautiful,” he added.

But don’t call it a feminist turning point for the brand, said Leibovitz, who also photographed a version of the Pirelli calendar in 2000, featuring nudes. “Pirelli has always given free rein to the photographer,” she explained, “so it’s really about choice of photographer.”
